To all 'Ju/7,0711, 'llt 11m/y con/007%;

Be it known that l, ALLAN C. RUSH, a citi- Zen of the United States,residing in the city of Los Angeles, in the county of Los J-lngeles andtitane of `California, have invented certain new and useful improvementsin Injector- Burncrs, of which the following is a specification.

This invention relates to positive and elli cient means forntilizingliquid hydrocarbon as fuel, and particularly to means forthor-- ougllly and completely atomizing said fuel.

rlfhe primary object of the invention is to provide an injector-burnerwhich while extremely useful shall be very positive and eilicient inoperation and in which all liability of clogging' or choking the burnerby carbonization will be avoided and which shall be simple and cheap inconstruction and which shall be peculiarly adapted for use with heavycrude hydrocarbon oilsmsuch as, for instance, the heavy crude asphaltunioils of California.

lo this end the invention consists in the constructions and combinationsof parts hereinafter described in detail, but particularly pointed outin the claims.

The invention will be more readily understood by reference to theaccompanying' drawings, forininga part of this specification, and inwhich Figure 1 is a plan view of a burner embodying my invention, thecap of the burner having been removed. lllig. 2 isa longitudinalsectional view el the line ffl X2 of Fig. 1. ldig. 3 is an inverted planview of the cap of the burner of the style shown in Fig. 2. Fig. a is aside elevation of a burner embodying' iny invention, showing anothermeans of retaining the cap or cover in position. Fig. 5 is an invertedplan view of a modified form of the cap or cover.

ris shown in the drawings, the casing 2 is provided with a chamber 3,and through the center of this chamber extends a pipe or cylindricalcasing ll, which may be integral with the casing 2, as shown in thedrawings, or may be removablyr secured therein. The rear end of thecasing 2 is open to receive the oil pipe 5, and the steam pipe (5extends through the pipe 5 into connection with the casing or pipe et,the pipes 6 and 11 forming the stcamway. rlhe casing 2 at its upper orouter end is closed by a suitable top 7, and this top or floor 7 isprovided at its center with an opening 8, registering with the way ll ofthe easing or pipe rlhe openilig Fi is preferably flared outwardlytoward its top, as shown, to provide for the expansion of the steam. Anannular channel 9 is provided on the top plate Y, as shown, and at thefront of the casing 2 this channel extends clear through the top platei' and into communication with the oil chamber o1' way 3, and forms theoiloutlet l0.

ll represents a spacer-plate adapted to be secured on the top plate Yand provided with a cutaway portion, so that the plate 11 forms, inefect, a segmental ring. 'lhe segmental ring 11 is so positioned on thetop plate that this cutaway portion is toward the open oilduct l0,

The easing 2 is provided at its upper end with an annular flange 12,which is flat on its upper face and extends out beyond the annularchannel 9. Vllhis flange 12 terminates be low the level of the uppersurface of the top plate "i', so that the upper face of the llange 'IQis slightly lower than the upper face of the plate 7.

i3 represents a member adapted to lit upon the upper end or top of thecasing 2. 'lhis member 13 is provided with an annular llange la,corresponding to the llange 12 of the casing?. and adapted 'te restthereon. The llanges 1Q and 14 are provided with suitable holes throughwhich bolts 15 are adapted to be insorted to hold the member 13 rigidlyin place with respect to casing The member 13 is provided with a bead16, adapted to rest in the annular channel 9.

lily reference to Fig. 3 it is seen that both flange 111 and bead .i6 ofthe member 13 are cut away at the front of the burner and over theannular oil-outlct 10, and that the niember 13 thus forms, in effect, asegmental ring, the eut-alvay segment of which controls the width of thellame from the burner, and that said cut-away portions substantiallycorre-- spend to the cutaway portions of the burnerplate 1l.

17 represents the cap or cover proper and is threaded, as shown at 18,to engage the correspondingly-threaded portions 19 of the member 13.This cap liis provided with an annular flange 20 above the threadedportion il, which ijirevents the cap being turned down into the member13 more than a certain distance. The head of this cap is either squaredor termed with sia sides for the application of a wrench, by which thecap may be screwed into place. '.lhe under surface of this cap isconcave, shown at 21, so that when the cap 17 is in place over thesteamway L1 an eXpansion-chamber is formed thereby. The use oi thespacer-plate 11 permits the cap 17 to be screwed down tight onto saidspacer-plate and the cut-away portion of the spacer-plate insures theformation oi' the steam-discharge slot 22 of the requisite verticalwidth. It is Obvious, however, that if it is desired to increase thewidth or this steam-discharge slot the same may be readily accomplishedby a partial turn oi the cap 17.

23 represents the partition in the center oi' the oil-discharge slot 10.This partition may be extended down into the oil way or chamber 3 or maybe terminated slightly below the surface of the discharge-slot 10.

In Fig. et I have shown a slightly-modilied form of my invention. Inthis modiiication I have shown the cap 17 held in place on the top oit'the casing 2 by means independent of the cap. This means consists inproviding a vcap-holding arm 23, provided at its forward end with a head24, the under surface of which is adapted to rest on the top of the cap.This arm 23 is provided toward its rear end with side lugs 25, and thepipe 'is provided with lugs 26, which extend up above the arm 23 and areprovided with undercut recesses 27, in which the lugs 25 are adapted torest. The arm 23 is provided at its rear end with a threaded hole, andin this hole a bolt 28 is adapted to work. By adjusting thc bolt 28 thearm 23 may be caused to hold the cap 17 forcibly in place on top of thecasing 2 or to release same, as may be required.

. The cap 17 of Figs. 4i. and 5 is substantially the union of the member13 and the cap 17 and is provided with a lange 14, corresponding toflange 14C, and with a bead 16@ corresponding to the bead 16, and with acutaway portion correspondingl to the cut-away portion of Figs. 2 and 3.In Fig. 5, however, I have shown the spacer-plate 11 as attached to theunder side of the cap 17 and the center oil the under side of said capconcave at 21', so as to form an expansion-chamber for the steam. Itwill be noted, Figs. 3 and 5, that the bead 16 of the member 13 extendsbeyond the edges of the cut-away portion. By thus extending the ends ofthe seg'- mental ring the upward and outward iiow of oil through the oilduct or outlet 10 is so regulated that oil is only permitted to flow outfrom the oil-duct at a point away from the edges of the cut-awayportion, and as the steam-discharge slot 22 is of the same width as thecut-away portion it is obvious that any possibility of the oil iiowingup over the edges of the cut-away portion is avoided and any possibilityof carbonization on the cut-away is absolutely eliminated.

The operation of the burner is as follows: The pipe G is connected witha suitable steamsupply, and pipe 5 connected with a suitable0il-supply,the oil being under slight pressure.

The steam passing through the steam-duct 4 and into theexpansion-chamber formed above the opening 8 is evenly supplied to thesteamoutlet 22 and lows over the face of the top plate and out over theoil-outlet 10 and draws the oil from the outlet 10 up into the steam, asthe face of the iiange 12 is somewhatlower than the face of the topplate 7. rIhe Object of-tlie partition 23 is to prevent the oil allrunning to one side of the slot 10 when the burner is tipped fromahorizontal positionas, for instance, when a locomotive is roundingl acurve or when the burner is used on a ship and the ship is pitching withthe sea.
